Ezurio in conjunction with Richco has designed a mounting pillar for use with the BISM II.  This allows the module to be securely held to a PCB using snap fit details.  Customer designs using these pillars should use 2.5mm diameter holes on a 1.6mm thick PCB; location details can be found in the BISM II User Manual.
